We ate at RFC DTD location the first night of our trip, took 15 min to get our waiter Wes to the table, then 15 min to get our drinks, then 30 for our appetizer. It wasn't just us either,all the tables around us were slow to get their orders. I will stick to the AK RFC, never had a problem there, so I can't say they are the best DTD restaurant.
Earl of Sandwich is very good , never had bad food there, and for desserts Ghiradellis, hands down, but then I'm a chocoholic!
